Romans 9:27

In that day the remnant of Israel and the survivors of the house of Jacob will no more lean on him who struck them, but will lean on the Lord, the Holy One of Israel, in truth.A remnant will return, the remnant of Jacob, to the mighty God.For though your people Israel be as the sand of the sea, only a remnant of them will return. Destruction is decreed, overflowing with righteousness. For the Lord God of hosts will make a full end, as decreed, in the midst of all the earth.

But what is God's reply to him? “I have kept for myself seven thousand men who have not bowed the knee to Baal.” So too at the present time there is a remnant, chosen by grace. But if it is by grace, it is no longer on the basis of works; otherwise grace would no longer be grace.

Yet the number of the children of Israel shall be like the sand of the sea, which cannot be measured or numbered. And in the place where it was said to them, “You are not my people,” it shall be said to them, “Children of the living God.”

In that day the Lord will extend his hand yet a second time to recover the remnant that remains of his people, from Assyria, from Egypt, from Pathros, from Cush, from Elam, from Shinar, from Hamath, and from the coastlands of the sea.

Therefore he shall give them up until the time when she who is in labor has given birth; then the rest of his brothers shall return to the people of Israel. And he shall stand and shepherd his flock in the strength of the Lord, in the majesty of the name of the Lord his God. And they shall dwell secure, for now he shall be great to the ends of the earth. And he shall be their peace. When the Assyrian comes into our land and treads in our palaces, then we will raise against him seven shepherds and eight princes of men; they shall shepherd the land of Assyria with the sword, and the land of Nimrod at its entrances; and he shall deliver us from the Assyrian when he comes into our land and treads within our border. Then the remnant of Jacob shall be in the midst of many peoples like dew from the Lord, like showers on the grass, which delay not for a man nor wait for the children of man.

shall we break your commandments again and intermarry with the peoples who practice these abominations? Would you not be angry with us until you consumed us, so that there should be no remnant, nor any to escape?

But now for a brief moment favor has been shown by the Lord our God, to leave us a remnant and to give us a secure hold within his holy place, that our God may brighten our eyes and grant us a little reviving in our slavery.
